More than 10 provinces have started to give COVID-19 vaccine booster injection. What is the function of strengthening injection?

Strengthening needles can prevent COVID-19 more effectively.

Boosters of COVID-19 vaccine are now encouraging more areas to receive booster injections of COVID-19 vaccine in many places. The so-called enhanced injection only plays a strengthening role on the original basis. Because COVID-19 vaccine is a preventive function, it is not certain. In September this year, an epidemic broke out again in Fujian. Fujian people have been vaccinated with COVID-19 vaccine, but they still get sick.

Need to strengthen the needle because the vaccine only plays a preventive role and cannot be effectively prevented, so it is necessary to strengthen the needle. It may play a role, which means that people will consider getting the flu vaccine after suffering from the flu. But after the flu vaccine, you will always catch a cold. This is because everyone's physique is different, and antibodies will be produced after vaccination.

Vaccination in COVID-19 Today's citizens should thank themselves for being born in China, because COVID-19 vaccine is free all over China. In some areas, subsidies will be given to encourage villagers to join COVID-19 vaccination. For these problems, it should be considered that COVID-19 vaccination is not only for personal benefit.

Does the booster needle have any adverse reactions? People will have some adverse reactions after being injected with COVID-19 vaccine. The most common adverse reactions are swelling and pain at the inoculation site. Some people will have fever, fatigue, nausea, headache and muscle pain after vaccination. These symptoms will last for 2~3 days and will recover on their own.

You should also observe some adverse reactions after half an hour of intensive vaccination in COVID-19, so you need to observe them at the inoculation point half an hour after vaccination, because serious adverse reactions often appear within half an hour after vaccination, so it is convenient to inform the doctor in time when observing at the inoculation point, and professional medical staff will handle them on the spot, which can effectively ensure their own vaccination safety.

What should I pay attention to when playing booster shots? Although strengthening injection will cause some adverse reactions, the probability of occurrence is not high, so don't worry too much. However, in some places, special attention needs to be paid when vaccination is strengthened. When the body has a cold and fever, it is forbidden to take booster vaccine. In addition, within three days after vaccination, try not to eat beef, mutton and seafood, do not eat spicy food, and try not to do strenuous exercise.
